NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent N o. 745,566, dated December 1, 1903.

Application tiled June 11, 1903. Serial No. 161,037. (No model.) I

To all whom, it may concern.' p

Be it known that I, IRAL NEWTON BURKE, a citizen of the United States, residing at Butcher Ranch, county of Placer, State of California, have invented an Improvement in Non-Refillable Bottles; and I hereby declare the following to be a full, clear, and exact description of the same.

' My invention relates to improvements in bottles and bottle-closures; and its object is to provide against the surreptitious refilling of a bottle once emptied oi' its original contents.

It consists of the parts and the construction and combination of parts hereinafter more fully described, having reference to the accompanying drawings,`in which- Figure l is a vertical central section of my invention. Fig. 2 is a section on lin`e a: of Fig. l. I

A represents a bottle having a neck 2, previded with a cylindrical opening, and an interior annular abutment or ledge 3, upon which the valve mechanism is supported. This valve mechanism comprises a cylindrical casing, 4 of glass, porcelain, or other suitable material,adapted to fit snug in the neck of the bottle. The lower end of casing 4 is open to receive the valve 5 and the valve-seat 6. The valve is in the form of a hollow truncated cone, preferably with concaved sides and having a hood 7 disposed over its upper open and contracted end and supported on Y studs 8. The interior of casing 4. is some- Whatcoutracted in its upper portion,and an annular groove 9 below the contracted portion affords space for a limited reciprocation of the valve between its seat and the shoula perforated top 13. The casing is permanently locked in the neck of the bottle by means of a corrugated band-spring 14, located in an annular groove'on the exterior periphery of the casing and adapted when the casing is inserted into the neck to interlock in a groove l5 in the neck.

In operation the valve mechanism is first assembled, the valve being slipped into the open end of the casing and the valve-seat subsequently screwed into or otherwise permanently secured, as by cement, in the casingsufcient room being left to permit of a limited reciprocation of the valve 6 to uncover ports 12 when the casing is inverted. After the bottle has been filled the `valve mechanism, with spring llli in position, is inserted into the neck and pressed down on ledge 3. Simultaneously the spring expands to engage in groove l5 and lock thecasing permanently in the bottle. The open end of the neck may be closed by a cork, as 16. To empty the bottle of its contents, the cork 16 is removed and the bottle inverted,whereupon valve 5 falls away from its seat and is supported at its cuter edge on ledge 10, as indicated in dotted lines, Fig. l. The liquid escapes in circuitous passage through opening l1, ports v2, opening 1'7 in the end of the valve, around hood 7, and out through the openings in top 13 of the casing. The moment the bottle is righted the valve falls back over its conical seat and closed ports l2.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a non-refillable bottle, the combination of a cylindrical valve-casing, a hollow, conical valve-seat located therein, a hollow conical valve inclosed in said casing and having a limited reciprocating movement, said valve substantially coaxial with said seat, said seat and valve having non-registering ports,

and means for locking said casing in the neck of the bottle.

2. In a non-refillable bottle, the combination with a neck having a substantially cylindrical opening, of a valve-casing seated in said opening, said casing inclosing a valvechamber, a valve in said chamber in the form substantially of a hollow truncated cone, and

IOO

a hollow Valve-seat conformable with said valve and with which seat the valve has a limited telescoping movement, said valve and seat provided with suitable ports.

3. In a non-refillable bottle, the combination of a valve-casing open at one end and having a perforated top portion partly closing the other end, said casing having a slightlyenlarged interior diameter at its lower end, a hollow conical valve -seat provided with ports located in said enlarged portion, a cap or valve normally resting on said seat and closing said ports and means for locking the casing in the neck of the bottle.

4. In a non-refillable bottle the combination of a casing seated in the neck thereof, said casing inclosing a valve-chamber, a valve in the form substantallyof a hollow truncated cone having an opening in its reduced end, a hood rigid with said valve and extending over IRA NEWTON BURKE.
